Journal ArticleDOI
Synthesis of congeners and prodrugs. 3. Water-soluble prodrugs of taxol with potent antitumor activity
Howard M. Deutsch,Jan A. Glinski,M. Hernandez,R. D. Haugwitz,Venkatachala L. Narayanan,Matthew Suffness,Leon H. Zalkow +6 more
TL;DR: Observations suggested that esters at C-2' and/or C-7, which would tend to promote water solubility, might serve as useful prodrugs of taxol, and salts had improved antitumor activity as compared to the free acids.
Journal ArticleDOI
Cuticular hydrocarbons ofReticulitermes virginicus (Banks) and their role as potential species- and caste-recognition cues.
Ralph W. Howard,C. A. McDaniel,Dennis R. Nelson,Gary J. Blomquist,Leslie T. Gelbaum,Leon H. Zalkow +5 more
TL;DR: A bioassay was developed to test the species-recognition hypothesis and the experimental results supporting the hypothesis suggest that cuticular hydrocarbons might serve as species- and caste- Recognition cues.
Journal ArticleDOI
Azodicarbonamide inhibits HIV-1 replication by targeting the nucleocapsid protein.
William G. Rice,Jim A. Turpin,Mingjun Huang,David J. Clanton,Robert W. Buckheit,David G. Covell,Anders Wallqvist,Nazli B. McDonnell,Roberto N. DeGuzman,Michael F. Summers,Leon H. Zalkow,John P. Bader,R. D. Haugwitz,Edward A. Sausville +13 more
TL;DR: Azodicarbonamide (ADA) as mentioned in this paper is a new compound that inhibits HIV-1 and a broad range of retroviruses by targeting the nucleocapsid CCHC domains.
Journal ArticleDOI
Supercritical extraction of taxol from the bark of Taxus brevifolia
TL;DR: In this article, the extraction of taxol from the ground bark of Taxus brevifolia using supercritical carbon dioxide and carbon dioxide + ethanol mixtures was studied and the extractions were preformed at 318 K and at pressures ranging from 18.07 to 25.79 MPa.
Journal ArticleDOI
Synthesis of pyrrolizidine alkaloids indicine, intermedine, lycopsamine, and analogues and their N-oxides. Potential antitumor agents.
Leon H. Zalkow,Jan A. Glinski,Leslie T. Gelbaum,Thomas J. Fleischmann,Laureen S. McGowan,Maureen M. Gordon +5 more
TL;DR: In this paper, (+)-trachelanthic and (+)-viridifloric acids were synthesized and their isopropylidene derivatives were regiospecifically coupled, at C-9, with (-)-retronecine obtained by hydrolysis of monocrotaline, isolated from Crotalaria spectabilis.
